SPECIFICATION forming part of Letters Patent No. 282,641, dated Application filed April 9, 1883. (No model.)

To all whom it may concern.-

Be it known that I, PETER H. J AOKSON, of the city and county of San Francisco, State of California, have invented an Improved Skylight,- and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in the construction of skylights for lighting purposes; and it consists, mainly, in a means for making tight joints where the parts meet, and providing against the effects of expansion and contraction, which loosen the joints and make cracks to leak and admit rain or wet.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1, Sheet 1, is an exterior view of an arched light embracing my. invention. Fig. 2, Sheet 2, is an enlarged view of the tileframes in which the glass is held, showing the manner of joining them. Fig. 3, Sheet 2, is a section of the same. Fig. 4, Sheet 3, is a transverse section of a rib, showing how the tiles are supported upon it and the joints formed. Figs. 5 and 6 are views of the ribs. Figs. 7 and 8 are views showing horizontal joints in the tiles.

The class of lights to which my invention is shown as applied in the present case are those in which frames of iron are supported upon curved or arched ribs, these frames having sockets to receive the glass, in the usual manner.

I make tight joints, and provide against the opening of cracks by expansion and contrac tion, by constructing the ribs a with flanges, or what I term roofing-pieces, b, which extend out upon each side, as shown in Figs. 4., 5, and 6. The tiles 0 are formed with araised ledge, d, which fits beneath the flange or roof I), and the tiles rest upon the flanges e at the bottom of the rib, being laid in abed of putty or any suitable cement. This raised ledge is of sufficient height to prevent an ordinary amount of water, in its course down the skylight, from entering the seam; but to preserve a perfectly-tight joint and provide for heavy rains, the spaces around the part (Z are filled with Portland cement, putty, white lead, or any form of fusible cement, which may be poured into the cracks or openings after having first fit- August '7, 1883.

ted a strip of wood along the edge to prevent its running out. This fills up the spaces at f, and the flanges I), projecting over, together with the raised ledges d, prevent any rain from getting most tile has a channel made in its edge, with lips or flanges g at top and bottom, into which the meeting edge of the next tile below may be introduced with a suitable cement to form a joint, as before described. The two edges are then held in place by bolts h, are plain and countersunk into the tile-frame from above, the lower ends being threaded to receive nuts, by which they are held in place. In Fig.8 a flange, g, from the upper edge of the upper tile lower one, and aflange, projects from the lower edge of the lower tile, beneath the up- 4 per one, the cement being applied between the two and the bolts h.

the headsofwhich projects over the edge of the I11 setting up this skylight, the ribs are first fixed in place ready to receive the tiles, and by leaving out the flange 1) upon each side of alternate ribs for a distance down from the top equal to the width of a tile, as shown at a,

Figs. 1 and 5, it will be easy to place one edge of each tile in the groove of the opposite rib and let it down into this open portion, from which it may be allowed to slide down to its place. The whole depth of the skylight from top to bottom having thus been filled, a strip of iron,

i, formed like the flanges b, is inserted in a slot made transversely through the rib to receive it, and when secured in place it forms a continuation of the ribs 12 upon opposite sides and holds the upper tiles in place.

Another method of setting up is to place'the first rib, the flange Z) being in this case left in- The second rib is set up with the first two, and,

tact. row of tiles in place between the after these have been fixed in place, the third .rib and second row of tiles, and so on until the whole has been completed. The lower ends of the ribs are supported upon the wall k, as shown in Fig. 1, and a gutter, l, is also partly supported upon this wall.

ted upon the top of the wall, having a lip, 11, bent down to overlap the inner edge of the A plate, m, is fit- I the tiles, and having the projecting overhanging flanges 72, substantially as herein described.

2. In a skylight, the tiles 0, fitted to the supporting-ribs, and having their lateral meeting edges 9 g, and the uniting-bolts h, herein described.

formed with the projecting flanges substantially as 3. In a skylight, the ribs a, with the channels to receive the edges of the tiles, and the projecting flanges b, said ribs having the flanges cut away at a, and slotted to receive the strips 73 after the tiles have been set, substantially as herein described.

4. In combination with the ribs a, resting upon the wall 70, the tiles 0, the gutter l, and the plate m, having the flanges or lips n and 0. substantially as herein described.

In witness whereof I hereunto set my hand.
